Summary
The aim of this course is to acquaint students with the use of optical fibers not only as a communication medium but also as a element suitable for sensory use. Students are familiar with the differences between communication and sensory fibers, division of fiber optic sensors, futhermore with the basic characteristics, principles and processes, which are using in these fibers for the sensory operation and also with practical applications of these sensors.
Learning Outcomes of the Course Unit
The understanding of the basic processes and principles of fiber optic sensors and their differences against communication optical fibers.
Learning outcomes are designed so that students should be able to understand and assemble basic demonstration laboratory tasks from the field of fiber optic sensors.
Course Contents
Lectures:
1) Difference between communication and sensory fibers, use of optical fibers and their properties as a sensors, division of kinds and types of sensors.
2) Description of the physical principles and processes utilized during sensing.
3) Optical light modulators for optical sensors.
4) Intensity sensors.
5) Interferometry sensors, Sagnac and Michelson interferometer.
6) Grating optical sensors, gratings production, use, sensors with transverse or longitudinal grating.
7) Polarization sensors, photoelastic effect.
8) DTS, Principle of OTDR, OFDR, Rayleigh, Raman and Brillouin scattering, principle of DTS.

Tutorials:
First introductory tutorial, security of work in the laboratory.
Six laboratory tasks during semester.
Two tutorials are reserved for tests during semester and spare laboratory measurements.
The last tutorial in the semester is reserved for spare test.

Laboratories:
1) Vibration measurement by fiber optic interferometer.
2) Electric current measurement by magnetostrict sensor
3) Temperature measuremet by DTS system.
4) Intensity sensors - vertical and horizontal displacement.
5) Measurement of Bragg grating temperature dependence.
6) Determination of colouring agent quantity in substance.
